Syba USB 4.0 Type-C 10G Ethernet Adapter

SKU CH-V74M-8X76Z

Adds a 10 Gb/s RJ45 Ethernet port via USB 4.0 Type-C with passive aluminium cooling and Thunderbolt 3/4/5 compatibility

  • Class10G, PCIE
  • Adds 10 Gb/s Ethernet through any USB-C port using the AQC113 chipset
  • Runs fanless with an aluminium heatsink for silent operation from 0 °C to 108 °C
  • Draws power from the USB bus so no external adapter is needed
  • Negotiates 10G, 5G, 2.5G, 1G and 100M speeds automatically over Cat 5e up to 100 m
  • Supports 9K jumbo frames, VLAN tagging and Wake-on-LAN for advanced networks

Portable 10GbE Adapter for USB-C Hosts

This bus-powered adapter adds a single RJ45 10 Gigabit Ethernet port to any computer with a USB Type-C port. It uses the AQC113 chipset and supports auto-negotiation at 10Gb/s, 5Gb/s, 2.5Gb/s, 1Gb/s and 100Mb/s Base-T. The aluminium enclosure doubles as a passive heatsink with open airflow gaps. It is compatible with Thunderbolt 3, 4 and 5 connections.

Passive Cooling and Bus Power

The adapter draws all power from the USB connection and requires no external supply. Its fanless design relies on the aluminium case and large ventilation gaps to dissipate heat during sustained transfers. Operating temperature is rated from 0°C to +108°C with storage tolerance down to -40°C. No moving parts mean silent operation in quiet workspaces.

Upgrade Path for Legacy 1GbE Links

The jump is worthwhile when moving from a built-in 1Gb/s port to multi-gigabit NAS, storage arrays or switch uplinks that support 2.5Gb/s, 5Gb/s or 10Gb/s over existing CAT 5e cabling up to 100 metres. It does not suit buyers who need a second simultaneous 10GbE port or desktop PCIe cards with lower latency. IEEE 802.1Q VLAN tagging and Wake-on-LAN are supported for managed environments.

Questions about this item

How do I install the Syba USB 4.0 Type-C 10G Ethernet Adapter and what step is often missed?

Plug the adapter into any USB Type-C port or at the end of a USB device daisy chain; the step often missed is confirming the host port supports USB 4.0 or Thunderbolt 3/4/5 so the 10 Gb/s link can negotiate.

What maintenance or replacement will the AQC113-based adapter need over time?

No routine maintenance is required; the fanless aluminum enclosure relies on passive cooling, so keep the ventilation gaps clear of dust. If the USB cable or RJ45 port wears out, the whole adapter is replaced.

What limit appears first during sustained 10 Gb/s transfers?

The operating temperature ceiling of 108 °C is the first hard limit; prolonged heavy throughput can push the passive heatsink toward that threshold, causing thermal throttling before any other bottleneck.
